(Qt)-Backstep.py is commandline and graphical (Qt) backup software written in pure Python. It can back up any directory to CD-R(W), DVD-R(W), USB key, or another directory. It is a continuous backup solution. It works like a time machine. It contains a backup network server. It can send backups over the Internet or your network.

A practical lambda-calculator is a normal-order evaluator for the untyped lambda-calculus, extended with convenient commands and shortcuts to make programming in it more productive. Shortcuts are distinguished constants that represent terms. Commands define new shortcuts, activate tracing of all reductions, compare terms modulo alpha-conversion, print all defined shortcuts and evaluation flags, etc. Terms to evaluate and commands are entered at a read-eval-print-loop (REPL) "prompt" or "included" from a file by a special command. A Haskell branch is an embedding of the lambda calculator (as a domain-specific language) into Haskell. The calculator can be used interactively within Hugs or GHCi.

a2b invokes conversion tools in sequence to convert files from one type to another, possibly performing some extra processing along the way. Itis a wrapper for many programs like gif2png, latex2html, netpbm, mencoder, ffmpeg, oggenc, etc., that can convert content from one type to another. It can covert text, documents, images, audio, and video and more. Some examples: a2b test.mp3 test.ogg; mencoder_opts="-ss 60 -endpos 10" a2b video.avi clip.flv; a2b -g=subtitles dvd://8 movie.sub; a2b -q http://sam.nipl.net/ sam.aac. That last example downloads the author's Web page, converts it to text with lynx -dump, speaks the text with flite or espeak, and converts the audio file to AAC with faac.

ACCORD is a C library for composition of SEM or scanning helium-ion microscope images with correction of drift. It is able to compose (average) large sets of extremely noisy images that were acquired by scanning charged-particle microscopes at the highest possible speeds (lowest pixel-dwell times). If the images are composed using traditional techniques, they usually become extensively blurry. The technique that is implemented in this software corrects these derogations by pre-shifting the composed frames.

The Robot AI Mind in JavaScript for Web migration and in Forth for robots is an artificial intelligence evolving towards full civil rights on a par with human beings and towards superintelligence beyond any human IQ.

AML is an implementation of a basic register machine coded in C++. It provides all of the rudimentary features of any machine language like basic I/O and arithmetic but provides a very easy syntax and its own portable binary compression scheme for storing files. AML is currently distributed on SunOS 5.5, Linux 2.2, and Win32 console.

AMT REST API implements all the functionality available in the Amazon Mechanical Turk API natively in PHP. There are no external dependencies. The package requires PHP 5.3 or later and uses namespaces. Optional sub-packages handle worker qualifications and notifications sent by the AMT service. The source is intended to be used with the docblox automatic documentation system. An HTML manual cross-links the internal documentation with Amazon's API documentation.

ASFRecorder is a tool which enables you to download and save streaming content in Windows Media Format to your hard drive. It consists of a console-mode application which can be compiled in Linux and SunOS.

AWK address collection is a collection of scripts to extract information from a
loosely formatted address file. It currently allows you to lookup addresses and
phone numbers, list category members, list birthdates and ICQ UINs,
automatically create a ~/.micqrc file with all ICQ users, and ~/diary with
birthday reminders from the address database. It can be extended very easily.
